That's just the plants. In the barn, Geraci wants to bring in goats, sheep, chickens and cows. He'd like to try beekeeping. And in the name of sustainability, he's counting on building a compost station and a worm farm.
It sounds ambitious. Geraci, however, is anything but daunted. He sees the entire plan - from mushrooms to worms - coming together in phases over the next year. Moreover, he believes the farm will be paying for itself in two years.
"It sounds like a lot of jabber," he concedes. "But it's very real. This is very doable."
The farm is part of Geraci's overall strategy to get city schoolchildren eating healthier meals and making them more aware of the environment and how their food choices affect it.
Like food directors at schools all over the country, he's cutting back on frozen entrees and making deals with area farms to get things like fresh Maryland peaches onto children's lunch trays. He jokes that before he got to town, the most important tools in the school kitchen arsenal were box-cutters. Earlier this year he instituted a "breakfast box" program to encourage kids who might otherwise skip the meal to instead grab the containers with milk, 100-percent juice, low-sugar cereal and a high-protein snack.
Baltimore recruited him this year from New Hampshire, where he led a public school food services department and founded a program called First Course, a culinary arts school for young people who are low-income, disabled or recovering from addiction.
Here, Geraci's job is fraught with challenges. Making good food is the easy part - it's getting children to make the right choices outside of school that's tough.
A 2007 survey found one-fifth of high school students in Baltimore City were obese, according to the city's Health Department. Students in the city were more likely to be overweight than those elsewhere in Maryland. And, rates of heart disease, high blood pressure and diabetes in adults are also higher in the city - particularly among blacks.
Nationally, obesity among children and adolescents has increased by about 66 percent during the past decade.
Geraci, who grew up in public housing in New Orleans and, in his adult life, has struggled with diabetes and weight issues, thinks he understands what the young people of Baltimore are up against. As he puts it, "I know what welfare cheese tastes like."
